Jim Miller 8818edbe2f Fix 6485058: remove OnTriggerListeners from Wave*Methods in cleanup
This fixes a rare crash that could happen when the device orientation
changes while the handle is held over a target.  LockScreen.cleanUp()
was being called which set mCallback to null which then causes it
to crash in MultiWaveViewMethods.onTrigger().

The solution is to also remove OnTriggerListeners in LockScreen.cleanup().
